Nokia Shared Data Layer & Subscriber Data Management
Nokia Shared Data Layer is a common repository where the applications can store all their data, including subscriber, charging, policy and session data. Like this, VNFs will become data-less and stateless applications.
Using this shared data, stateless VNFs enable more rapid innovation of services and faster revenue growth through better insight into subscriber behavior. This insight in turn helps operators to develop innovative and customized services, generating more revenue.
The new architecture separates the data storage from the service logic to introduce a fully virtualized, distributed, geographically redundant and strongly secured Shared Data Layer. This will store and make available all the data required by the VNFs, including subscription data, policy data, charging data and session data, which includes VNF state information. The data held by the Shared Data Layer will be accessible by the network’s family of VNFs via industry standard protocols. Consolidating all the data into one layer also makes it easily available through standard northbound interfaces to data analytics and third party applications
Shared Data Layer simplifies cloud operations, allowing simpler upgrades, scaling and failovers, as well as the integration of new applications. For example, should one VNF fail or suffer a problem, another VNF can be activated and immediately access the same data held in the Shared Data Layer to maintain a seamless service.
Operators using Shared Data Layer can monetize data exposure to generate new revenue streams enabling new services.
Nokia Subscriber Data Management complies with the 3GPP User Data Convergence standard to centralize user data into a single, robust and secure User Data Repository (UDR). The suite of Nokia front-end applications, such as our combined HSS/HLR solution for 2G/3G/4G and IMS, our One-EIR and One-MNP, but also our AAA, PCRF and even third party applications, can then access the data from the shared register. The result is a central register with single point of provisioning, which saves costs and speeds up time to market dramatically when introducing new technologies or new services or when activating new customers – while also offering unparalleled scaling capabilities able to meet the most stringent requirements.
Nokia Subscriber Data Management offer extremely high availability, reliability and performance and also prepares the way for future network evolution towards the telco cloud and 5G. With virtualized front-end applications already available and smooth evolution toward Nokia Shared Data Layer (SDL) to fully realize the benefits of the cloud, your investment is preserved and you can upgrade your network at the pace that best suits your needs.
Shared Data Layer is one of the main building blocks of the Nokia cloud-native core. The Nokia cloud-native core network is explicitly built and optimized for cloud. Cloud-native core offers the flexibility, responsiveness and adaptability needed to deliver the high performance, ultra-reliability and low latency demanded by IoT and 5G.
